PEEK Filled PTFE is a high-performance engineered PTFE grade reinforced with PEEK fillers to deliver superior mechanical strength, outstanding wear resistance, enhanced dimensional stability, and improved thermal performance compared to virgin PTFE. It is widely used for precision CNC components, bushings, bearings, seals, and wear parts operating under combined load, friction, and elevated temperatures in heavy industrial environments.
What Is PEEK Filled PTFE?
PEEK Filled PTFE is an advanced reinforced PTFE material engineered by incorporating
PEEK fillers into the PTFE matrix. This combination significantly enhances mechanical strength,
wear resistance, dimensional stability, and load-bearing capability while preserving PTFE’s low friction
and excellent chemical resistance.
This grade is specifically developed for applications involving
high mechanical loads, continuous sliding, elevated temperatures, and chemically aggressive environments,
where standard PTFE grades are no longer sufficient.
Key Engineering Properties
- Exceptional mechanical strength: Suitable for components exposed to heavy loads and stress.
- Outstanding wear resistance: Stable performance in severe sliding and friction conditions.
- Excellent dimensional stability: Minimal deformation under heat, pressure, and long-term service.
- Wide thermal operating range: Reliable performance from approximately -200 to +260 °C.
- Improved compressive strength: Ideal for bushings, bearings, and load-carrying parts.
- High chemical resistance: Maintains PTFE’s resistance to most aggressive industrial media.
- Extended service life: Designed for continuous-duty industrial systems.
